Application filed'January 3, 1906.- Serial No. 2534,4111.v I

This invention relates to certain new and useful improvements in:conveyors, and the invention relates more particularly to a con:-

veyer'adapted to be used'ina connection with the rol'lsoi tin-mills,merchant-mills, and the like manuiacturingrmills;

The-primary object of'my invention is the provision of novel means fortransferring a piece of material or work from the passesoi a pair-ofrolls to a placewhere the piece can be easily gripped and again passedthrough the same rolls.

My invention aims: to provide a conveyor wherein novel-z'means isemployed for grippmgaa. piece of'work. and conveying it toa desiredpoint, and this connection my iI'Ilrproved conveyer is intended to "beused in: connection with tin-ningrmills, wherein sheets of tin,:or, asit isknown tothetrade, a pack is passedthrough rolls a number of times,it reqluiringj a workman upon each side of therol s tomanipulate thepack as it passes between the rolls. o

My invention aims to dispense with a workman uponone side of the rollsand a;

provide a conveyer to receive the piece as it passes through the rollsand convey it over the top of the rolls, where it may be gripped andagain passed between the rolls: To this end- I have devised a conveyoradapted to be driven by the rolls in: connection with which it is used,meanszha-ving been: devised to grip the pack and: automatically releasethe same at a predetermined time. I have also provided means foradjusting the conveyer for ,d'iflerent sizes of'packs, and during theentire operation of the conveyor it will not be necessary for a workmanto give it his attention except when it is to: be adjusted to receivelarger'or smaller packs" I With the above and other objects in view,which will morereadili y appear as thenature of the invention is better:understood, the sameconsistsin thenoveli construction, combination, andarrangement of parts,.tobe hereinafiter more fully described and thenspecifically pointedout the claims, and, re.-

In the accompanying drawings haveillustrated' two housings 1 1, betweenwhich are journaled rolls 2' and 3,. said housings and rolls being of aconventional form, such as are generally used tinning millsi Myinvention resides in providing the housings upon one side of the rollswith outwardly-extending guideways 4 4, said guideways being inclinedupwardly, as illustrated in Fig; I of the drawings, and havingtheirouter ends supported by legs 5- 5,. which are suitably braced, asat 6 while the: inner ends oi said 'guideways are secured tow the edgesof the housings 1 11,, as. at Z. The guid'cways are further braced: bysingularly-disposed; bars 8 bolts and nuts 14, which extend-between thestrips 11. 1-1 of each guideway. Thesplatel '2 is: provided withoutwardly-extending portions 1 5 L 5,. these portions forming afoundation forthe gripping mechanism 16: of my improved conveyer. Uponthe plate 112 are mounted two brackets 1'2 1'2, in: which is Journaled'upon the pin 18 is a curved gripping-head 1 9 the lower end of saidgripping head extending; into a slot 20;. formed in' the portion 15 ofthe plate 12. Pivotally mounted: upon the plate. 12 between lugs 2.1 21Visa curved chain-grip 22., carryinga hook-shaped member 23-, the objectof whichv will bepresently described The chain-grip; 22* ispi-vota-llfyconnected by a link 24 with thelower end of the griprhead 1'9-,.-saidlink extending betweenthe. brackets 17 L7 into-theslot. 2.0-of theplate1.2

V The singularly-disposed bars 8- 8 adjacent to the housings. areprovided with bearings 25 25, which! a shaft2i6dsjournaledz. The legs 55Iat: the outer end; of the conveyor are 8', which are secured totheguid'eways, as. at

IIO

provided with adjustable brackets 27 27, in

which a shaft 28 is journaled. Upon the shafts 26 and 28 are mountedsprocketwheels 29 and 30, respectively, and over said wheels is adaptedto pass a sprocket-chain 31. Upon the end of the shaft 26 is mounted asprocket-wheel 32, over which passes a sprocket-chain 33, that engages asprocketwheel 34, mounted upon the neck of the roll 3.

Slidably mounted upon the guideways 4 4 is a cross-head 36, saidcross-head being slidably connected to the guideways 4 4 by bolts andnuts 37 37, similar to the bolts and nuts 14 of the plate 12. Thecross-head is pro- 'vided with upwardly-extending prongs 38 38 and witha depending strap or stirrup 39. Connected to the strap or stirrup 39 isa cable 40, which passes over a pulley 41, journaled in a bracket 42,carried by a transverse bar 43, secured to the housings 1 1. The lowerend of the cable extends into the housing-pit 44 and is provided with aweight 45, whereby the cross-head 36 will be normally held in en-'gagement with stop-blocks 46 46, carried by the outermost strips 11 11of the guideways Adjustably mounted upon the guideways 4 4 by bolts andnuts 47 47 is a transverse bar 48, said bar being employed to limit therearward movement of the head 36, the ob v ject of which will bepresently described.

vers'e guide-roller 52.

The housings 1 1 are provided with inwardly-extending brackets 49 49,and secured to} said brackets are outwardly-extending guide-rails 50 50,said rails being provided with hinged members 51 51 and with a trans-The hinged members are adapted to lie in engagement with the guideways 44, as clearly illustrated in Fig. l of the drawings, and the use ofthese hinged members will be presently described.

The housings 1 1 adjacent to the pass between the rolls 2 and 3 areprovided with a transverse bar 53, carrying guide-plates 54 54, which;extend inwardly in close proximity to the pass between'the rolls 2 and3.

The lower face of the plate 12 is provided with a pierced lug 55, andconnected to said ,lug is a cable 56, which passes over a pulley 57,journaled in the bracket 41, said cable eX- tending into the pit 44ofthe housings and having a weight 58 upon its lower end.

' smasplate 12. The movement of the grip-head in engaging the packcauses the chain-grip 22 to descend through the medium of the link 24,and the end of the chain-grip engages in, the chain 31, which will carrythe plate 12 upwardly upon the guideways 4 4. As the plate 12 movesupwardly it strikes the crosshead 36, and the cross-head ascends uponthe guideways, together with the plate 12, until the bar 48 is reached,which limits its movement, said. bar also serving to release thechain-grip 22 by striking the hook-shaped member 23 of said grip. Afterthe release of the chain-grip the plate 12 is allowed to descend to itsnormal position, together with the cross-head 36, this beingaccomplished through the medium of the weights 45 and 48, suspended inthe pit 44 of the housings. As the plate 12 and the cross-head 36 ascendthe pack passes beneath the hinged members 51 51, and when the plate 12and the crosshead 36 descend the rear end of the pack travels upwardlyupon the hinged members 51 51, upon the roller 52, and upon the rails 5050. The plate 12 is adapted to pass beneath the hinged members 51 anddescend to its normal position in close proximity to the pass betweenthe rolls 2 and 3, the extremities of the hinged members 51 51 beingslightly upturned, so that while the pack will travel upwardly on thesemembers the plate 12, which has its front edge beveled, as shown in Fig.1, will pass beneath the same, while the cross-head 36 will be retainedby the stop-blocks 46 46. The gripping mechanism 16, having assumed itsnormal position, is in condition to grip another pack passed through therolls 2 and 3, but may grip the pack again which has been passed overthe top of the roll 2, said pack being received by a workman and againfed between the rolls 2 and 3. The prongs 38 38 upon the crosshead 36are employed for bracing a pack during its upward movement upon therails 50 50, and the plates 54 54 are adapted to guide the pack from thepass between the rolls 2 and 3 to the plate 12. In case a very long packis passing through the rolls the stopblocks 46 46 are adjusted in orderthat the pack will not be forced too far from the roll 2, and thetransverse bar 48 is also adjusted, to permit of the cross-head movingsufficiently to accommodate the entire pack upon the guideways 4 4between the bar and the hinged member 51 51.

From the foregoing it will be observed that I have devised novel meansfor manipulating pieces of material passed between rolls where it isdesired to again repass the material, thus dispensin with laborheretofore employed to accomplis 1 this result.

I do not care to confine myself particularly to a tin-mill, as the samemay be readily employed in merchant-mills and rolling-mills, where anumber of passes are employed for lIO rails and resting upon saidguideways, a gripping mechanism carried by said plate and. adapted to beactuated by a pack passing be tween said rolls, means engaged by saidgrippin mechanism to convey said plate, said pac: and said cross-headupon said guideways, means to release said gripping mechanlsm, and meansto return sa1d plate and said cross-head to their normal position,substantially as described.
